Hertel E1039032 Square End Mill 1/2 in 4 Flute Hss

Product Description

The HERTEL E1039032 is a 4-flute square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Manufactured from M7 high speed steel in an uncoated finish, it features a 30-degree spiral helix and a right-hand cut with right-hand fluting. The 0.5 inch cutting diameter and 1.25 inch length of cut make it well-suited for slotting, profiling, and peripheral milling. The centercutting geometry allows it to plunge directly into a workpiece without a pre-drilled hole. This tool is installed and operated by machinists and CNC operators in job shop and production settings.

This end mill is configured for use in conventional milling machines, CNC machining centers, and manual knee mills where a 0.5 inch shank is accepted. The 3.25 inch overall length provides adequate reach for standard-depth setups without excessive overhang. The regular-length designation and spiral flute design support efficient chip evacuation in ferrous and non-ferrous materials. It is sold as a single unit and is appropriate for shops running steel, aluminum, cast iron, and similar machinable alloys.

Key Features

• M7 high speed steel construction for durability in general-purpose cutting applications
• 4-flute design balances chip clearance and surface finish quality
• 30-degree helix angle promotes smooth cutting action and reduced chatter
• Centercutting geometry enables direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute configuration for standard spindle setups
• Uncoated finish suitable for use with cutting fluids in a range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use end mill for milling machines and machining centers that accept a 0.5 inch straight shank toolholder.

Installation Notes

Install by a qualified machinist or CNC operator using a properly sized collet or end mill holder rated for the 0.5 inch shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Minimize tool overhang beyond the holder to reduce vibration and deflection. Verify spindle rotation direction is set to right-hand before engaging the cut.
